摘　　要：在大坝基岩坝基防渗帷幕灌浆施工中,其帷幕成孔质量直接关系到帷幕幕体的质量,需要对孔斜产生的各类原因进行分析后采取合理的措施进行控制。为了保证长河坝水电站深孔帷幕成孔质量,其前期质量控制措施之一为采用测斜仪监控孔斜,并结合生产实际需求对测斜仪进行选型。本文阐述了KXZ-1A型数字测斜仪在长河坝水电站深孔帷幕灌浆成孔质量控制中成功运用的情况,旨在为水电站深孔帷幕钻孔成孔质量控制提供一种切实有效的方法。In the construction of anti-seepage curtain grouting for dam bedrock foundation,the hole forming quality of the curtain is directly related to the quality of curtain body,so it is necessary to take reasonable measures to control the hole deviation after analyzing various causes.In order to ensure the hole forming quality of the deep hole curtain of Changheba Hydropower Station,one of the early quality control measures is to use the inclinometer to monitor the hole inclination and select the inclinometer according to the actual production demand.This paper describes the successful application of KXZ-1A digital inclinometer in the quality control of deep hole curtain grouting in Changheba Hydropower Station,aiming at providing a practical and effective method for the quality control of deep hole curtain drilling in hydropower stations.
